I SANITARY CREAM SAVER.

Application filed November 22, 1926. Serial No. 150,055.

The invention relates to a sanitary cream Fig. is a plan view of the device, the saver. sprlng being in section. The object of the present invention is to In the accompanying drawin s, in which provide a simple, practical, and eflicient is illustrated thepreferred em odiment of Tsanitary device of strong, durable and comthe invention. the sanitary cream saver paratively inexpensive construction. designed comprises in its construction a rod or stem for separating the cream in a milk bottle, 1 which is round in cross section and which from the milk thereof and capable of being has a lower threaded end 2 screwed into a readily introduced into a milk bottle withthreaded opening 3 of a hard rubber disc 4 5 out causing any material mixing of the carried by a thin circular flexible disc'5.

A further object of the invention is to Within the central portion of the soft rubber provide a sanitary device of this character disc 5, the soft rubberbeing molded around which will not require hinge joints, nuts, the hard rubber disc 4 and completely cover-- washers, and similar fastening devices 'ing the same-at the upper and lower faces which gather milk or cream and render rethereof, as clearly illustrated in Fig.2 of moval thereofdiflicult, and thereby impair the drawing. The hard rubber disc is pref the sanitary character of the device bythe crably tapered in .thickness at its periphsouring of such lacteal' accumulation. cry, as shown, and the softrubber disc 5 It i also an object of the invention t prois slightly thickened at its lower portion vide a cream separating device adapted to whene, it is molded '3 around the central b il i l t d for'breaking the sucthreaded disk 4.

hinge joint. Also the spring connection has the function of automaticallyreturning the disc to its normal position at right angles to the stem after the disc has beenintroduced into the bottle and passed through the cream portion thereof'and has reached the interior of the bottle at the cream line. As soon as the disc is free to assume its normal position with relation to the stem the spring will operate to carry itfrom the position shown in Fig. 3 of the drawing to a hori- When the disc has assumed a horizontal position at the cream line it separates the cream from the milk and the cream is adapted to be poured out of the milk bottle without the removalof any of the milk, and all of the cream may be saved. After the cream has been poured oil the milk, the suction' between the disc and the milk may be readily broken by pushing the stem to one side of the bottle and pressing downward on the stem, whichthrough the action of the spring will cause the disc to separate itself from the bottle at the periphery by a simple bending or flexing of the disc. This will result in withdrawing the edge from the interior wall of-the bottle at one side and will break the suction and enable the device to be easily and quickly removed or a portion of the milk poured oil as desired. In practice, the stem will be made offine spring steel and the flattened portion 6 will result in a fine steel spring which will not only dispense with the hinge joint heretofore employed for enabling the disc to be arranged at right angles to the stem, but it will also automatically operate the disc in returning the same to its normal horizontal position and in breaking the suction after the cream has been poured otf.

The stem is provided with a handle or finger loop 8 of circular form having a lat- The thin flexible rubber.

This not only prevents any lia- I erally extended pointed terminal 9 diverging from the plane of the loop and adapted to readily penetrate a milk bottle top for enabling the same to be easily removed from a milk bottle. By placing the finger loop or handle in a horizontal position upon a milk bottle, the projecting terminal portion 9 may be readily caused to pierce the milk bottle top and the stem may then be operated as a lever for lifting the top without causing any splashing of the milk or cream.

I claim:

.1. A sanitary cream saver comprising a flexible disc adapted to be inserted in a bottle or other receptacle, and a stem connected at the lower end to the dlTIC and provided with a spring constituting a portion of the length of the stem and permitting the stem to be flexed to arrange the disc at an angle to its normal position and capable also of automatically returning the disc to its normal position after the same has been introduced into a receptacle.

A sanitary flexible disc adapted to be inserted in a bottle or other receptacle, and a stem connected at its lower end to the disc and pro vided with an integral reduced portion forming a spring and permitting the stem to be flexed to arrange the disc at an angle to its normal position to permit the disc to be inserted edgewise into a receptacle.

3. A sanitary cream flexible disc adapted to be inserted in a bottle or other receptacle, and a stem connected at its lower end to the disc and provided above the same with a flattened portion forming an integral spring adapted to be flexed to permit the disc to be arranged at an angle to its normal'position for introducing the disc edgewise into a receptacle and for causingthe flexing of the spring within a bottle, being adapted to flex the disc and break the suction between the disc and the liquid below it. Y

.4. A sanitary cream saver including a flexible disc provided with a centrally arranged core embedded within the disc and having a threaded opening, and a stemhaving a threaded lower end screwed into the threaded opening ofthe said core.
